We propose a high-dimensional LASSO (Hi-LASSO) that theoretically improves a LASSO model providing better performance of both prediction and feature selection on extremely high-dimensional data. ... The Hi-LASSO was also applied for survival analysis with GBM gene expression data. INDEX TERMS Hi-LASSO, LASSO, random LASSO, high-dimensional data, variable selection. 44562 2169-3536 ... CONCLUSION We proposed a novel High-dimensional LASSO (Hi-LASSO) for variable selection in a linear regression model with extremely high-dimensional data. ...doi:10.1109/access.2019.2909071 fatcat:wrsmupelcffo3ob4ovnxvu7j4y
Under a new irrepresentability condition, we show that the new loss function with the lasso penalty can give consistent estimates in high-dimensional setting for sub-Gaussian and polynomial-tailed distributions ... By adding a lasso penalty to this D-trace loss, we can estimate the precision matrix difference in high-dimensional setting. ... Teng Zhang for his discussions about his asymptotic property in his lasso-penalized D-trace loss. ...arXiv:1511.09188v2 fatcat:pbut4uoc4be4xbhhafurhtufwu
The idea is a natural extension of the LASSO technique proposed by Tibshirani (1996) and is based on the (joint) residual sum of squares while constraining the parameter estimates to lie within a suitable ... LASSO method. ... σ l α = p l=1 i∈σ l |β i | = m l=1 |β l | = β 1 and the constraint (2.1) reduces to the L 1 -norm of the complete vector of parameter estimates, which is the constraint used by Tibshirani (1996) in his ...doi:10.1198/004017005000000139 fatcat:6k25aejanbbgjp6t74lugy2ola
lasso, the low contact force, which can limit the size of the lesion, and the use of an additional sheath for ablation, as well as the cost of the procedure compared with the manual lasso technique. ... Other high-performance tools may be used with this magnetic robot system and are undergoing constant development. This should further improve ablation results and also reduce procedure times. ...doi:10.2147/mder.s96167 pmid:27698569 pmcid:PMC5034914 fatcat:wi3325kmnjgljkzld4sgz3r444
Such scenarios can be accounted for by adding an penalty in (49) on the individual blocks  , an approach that is dubbed C-Hi-Lasso in  . ... This necessitates a high bandwidth track and hold device, which is difficult to build at high frequencies. ...doi:10.1109/tsp.2011.2161982 fatcat:mlbtksjmqvbmfmi6gpxwtunbti
Doolittle, they fl ew to northern Sweden for the annual reindeer hunt, where "a Laplander and his lasso" captured a few specimens from which blood was drawn. 120 They also traveled Sweden's northern islands ... Similarly, the PDB has been used to classify proteins according to their three-dimensional shape. ...doi:10.1086/667832 fatcat:glwyszzxbfdspmtdi3w5lszx2y
